PROBLEM TO BE SOLVED: To provide a quality improver for adding to boiled rice, improving adhesiveness to a machine for mass-producing processed rice products and moldability, improving loosening properties of boiled rice to an extent, for instance, of facilitating measuring, and retaining the original texture and taste of boiled rice, and a method for producing boiled rice which is improved in quality together with loosening properties, and improved in quality such as texture and taste together with loosening properties.SOLUTION: A quality improver for boiled rice comprises a quality improver to be added to boiled rice, and contains dextrin as the major component. Dextrin as a hydrolysate of starch contained in boiled rice is added to boiled rice after boiling so as to be a film of liquid and be held on the surface of moisture-containing rice grains, the stickiness of rice grains is moderately reduced so as to make boiled rice easy to be loosened, and easy to be collapsed in the mouth when chewing to become easily eatable, and adhesiveness to a boiled rice processing machine is suppressed so as to improve workability and moldability in food processing.SELECTED DRAWING: None
